    After researching a ton of solar companies and getting a million quotes, working with John at Helios Solar Energy was a total breath of fresh air. What drew me to them were the great reviews, and they definitely lived up to the hype. Right from our first conversation, John was super detailed, never rushed me, and answered all my many questions with zero fluff. He was always quick to return calls, and his crew was awesome—really polite and great about cleaning up all the construction mess. Even when we hit a supply chain issue with the panels, John was totally straightforward and went way out o

    After a different company left me in the dust, John was so helpful and exactly what I was looking for all along. He quickly got the ball rolling to get my solar project done on a great timeline. I was very happy with the general timeline and his strong communication throughout. It was easy to text/email John, and he answered all the questions I had throughout the process. The installation in the fall was great and I’m now (in April) already getting more in solar sent back to the grid than I’m using. Exciting. It was important to me to support a small business. You’ll be treated like a good fri

    John and his team worked hard to learn from every hiccup, and when we got down to the wire on December 31st, he showed up and made it happen so I earn my federal credit. Obviously the process wasn't always smooth, and there were definitely some nervous moments along the way, when market was extremely competitive and distributors pivoting to meet 2025 deadline. John tho made it happen What you should know about Helios: · Best value I found – significantly lower pricing than other quotes for comparable equipment · Committed to learning – when issues came up, John dug in, asked questions, and fig

Topics Google derives from the review text, with how often each appears. A frequent topic is not a good one: “price” turns up in praise and in complaints alike.

What the company says about itself

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

  • Family owned

    “at an affordable price. We are a family owned business located on the Massachusetts…”

Its website also mentions warranty and free estimate, but not in a sentence we can quote cleanly.

Elsewhere

  • It is also reviewed on Yelp. Worth reading before you sign anything: those are a different crowd, and the complaints that reach the Better Business Bureau rarely reach Google.
  • It posts on Instagram and Facebook. A page that stopped posting years ago tells you something a listing will not.

Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

What we don't know

  • The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
  • We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
  • We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
